Which statement about essential nutrients should the nurse include?

Correct Answer: C

Rationale: The correct answer is C because carbohydrates are indeed the primary source of fuel for muscles and the brain. Choice A is incorrect because while certain fats are essential, they do not help decrease triglyceride levels. Choice B is incorrect because animal sources of protein do not contain all 20 essential amino acids. Choice D is incorrect because although high-fiber foods are important for digestion and overall health, they are not a direct source of energy.

Correct Answer: A

Rationale: Thiamine deficiency, also known as Vitamin B1 deficiency, can present with various symptoms. Tachycardia, muscle weakness, and lack of coordination are classic signs of thiamine deficiency due to its role in energy metabolism. Swollen lips, cracks in the corners of the mouth, and glossitis are more indicative of a deficiency in riboflavin (Vitamin B2). Neuropsychiatric symptoms of delusions and hallucinations are characteristic of niacin (Vitamin B3) deficiency. A scaly rash on the arms, dementia, and diarrhea are not typically associated with thiamine deficiency. Therefore, the correct assessment findings for a client with thiamine deficiency are tachycardia, muscle weakness, and lack of coordination.

Correct Answer: C

Rationale: In kidney disease, patients are advised to limit the intake of phosphorus. High levels of phosphorus can be problematic as the kidneys may not be able to effectively filter it out, leading to bone health issues. Calcium (Choice A) is important for bone health, but its restriction is not typically necessary in kidney disease. Magnesium (Choice B) and potassium (Choice D) restrictions may be required in certain cases of kidney disease, but phosphorus is the mineral most commonly limited due to its impact on bone health.

Correct Answer: C

Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.

Correct Answer: B

Rationale: Reducing sodium intake is the most beneficial dietary approach for managing hypertension. High sodium intake can lead to increased blood pressure, so lowering sodium intake is crucial in managing hypertension. Choices A, C, and D are incorrect because increasing caffeine intake, dietary cholesterol, or reducing fiber intake are not recommended dietary approaches for managing hypertension and may even have adverse effects on blood pressure levels.
